This study compares the buying patterns of American and Korean female college students in relation to their self-concept. It was implemented through self-administered questionnaires which were back translated for validity. Respondents comprised 730 female students majoring in fields related to clothing and textiles: 307 U.S. students were located in the Northeast, West, and Southwest, and 423 Korean students were at four universities in Seoul. Likert scales were used for most measures, with 1 = never or very unimportant, and 5 = always or very important. Personal self-concept was measured on the basis of Won-Shik Jung's Standardized Self-concept the Test and Tennessee Self Concept Scale. Data were analyzed by descriptive statistics and t-tests. Some clear differences between the two countries emerged. Marketers targeting American consumers should pay more attention to practicality and service, and for Koreans, more symbolic meaning of products and store displays, since these are important to them. Self-concept was somewhat related to purchasing behavior, but more study should be done before applying findings to marketing concepts.

Since 2000, there have been many changes in the residential types, such as an intelligent apartment which integrates both resting space and production space with comfort able, pleasant and safe environments based on internet systems. As the result of the rapid decrease in the birth rate and the prolonged lifespan around the world, it is expected that we will enter into an aging society by 2026. With such the expected change in the living patterns, many issues concerning the increased number of the elderly people have emerged as major social problems such as changes of family formation, its function and values, responsibility of caring for the aged, health and medical care, habitation policies and so on, and it is required to reconsider the social awareness on the living qualities of each old person. However, we have not yet satisfied such requirements with appropriate policies for the improvement of the living environment for them. It is considered, therefore, that we need to develop a new tool that, according to our goals, can give us a broad understanding on several considerations in designing the future homes for the elder people, making it possible to check the process changed by residents' needs in real time and apply it immediately to the space. As we have seen, it is required that spatial design process and design methodology should be considered in designing the homes for the aged for the pre-occupancy design evaluation.

Purpose of this study is to draw policy implications for family resource management's strategies and leisure culture revitalization to Korean baby-boomers. This study review leisure activities characteristics of Korean baby-boomers and find their characteristics' impact on leisure economy. This research analyzed with raw data of "National Research Leisure Activities 2012" in different methods: analysis of frequency, multiple regression analysis, Correspondence Analysis, and etc. As a result, compared to all age groups in Korea, Korean baby-boomers current participation in leisure activities is low, but their expense on leisure is high. Their leisure activities are varied from different genders to their incomes. Especially, baby-boomers, who are on high income, participate in wasteful leisure activities and their consuming behavior will be the mainstream of Korean leisure economy, so economy, which is aiming for baby-boomers, will be invigorated when the economy is more concerned with use values toward time. Particularly, preparing for the retirement of baby-boomers, further researches based on integrated family policy should be considered plans and efforts on encouraging active volunteer works and participation in leisure culture revitalization of Korean baby-boomers.

The use of Carbon Fiber Reinforced Polymer (CFRP) to strengthen steel structures has attracted the attention of researchers greatly. Previous studies demonstrated bonding of CFRP plates to the steel sections has been a successful method to increase the mechanical properties. However, the main limitation to popular use of steel/CFRP strengthening system is the concern on durability of bonding between steel and CFRP in various environmental conditions. The paper evaluates the performance of I-section steel beams strengthened with pultruded CFRP plate on the bottom flange after exposure to diverse conditions including natural tropical climate, wet/dry cycles, plain water, salt water and acidic solution. Four-point bending tests were performed at specific intervals and the mechanical properties were compared to the control beam. Besides, the ductility of the strengthened beams and distribution of shear stress in adhesive layer were investigated thoroughly. The study found the adhesive layer was the critical part and the performance of the system related directly to its behavior. The highest strength degradation was observed for the beams immersed in salt water around 18% after 8 months exposure. Besides, the ductility of all strengthened beams increased after exposure. A theoretical procedure was employed to model the degradation of epoxy adhesive.

Overheated speculation areas which have high potential of becoming speculative are the target of many real estate policies. This paper proposes a model for spatial patterns of house price volatility and suggests a spatial pattern of overheated speculation areas. House prices are determined by economic behaviors of sellers and buyers who have rational or adaptive expectations. Spatial patterns of house price volatility are formed by tendencies of their economic behavior. If there is a majority of adaptive sellers and buyers in an area, it may appear as a "hotspot" by showing high volatility of house prices and simultaneous price increases. Overheated speculation areas are formed by adaptive sellers and buyers who want to realize maximum expectation profit, therefore these areas patterns are defined as hotspot patterns of price volatility.

The purpose of this study is to segment urban farming patterns and analyse the preference on urban farming by applying two-step cluster analysis, chi-square analysis and ANOVA. The data was collected by face-to-face surveys on 9 urban farms which were chosen by location and operator. Respondents were asked to describe their urban farming pattern, preference on urban farming and socio-demographic characteristics. Three different clusters were derived from two-step cluster analysis based on operator, transportation, number of visits per month, travel time, area and motive. They were 'hobby-oriented farming', 'producing-oriented farming', and 'multipurpose farming'. The results of chi-square analysis showed that there were significant differences among these three segmented groups in terms of age, with or without children aged under 14, household income per month and housing type. In other words, there is quite a possibility that urbanites have different urban farming patterns according to their socio-demographic profiles. Also, there were significant differences on the preference on urban farming by cluster. According to the results, planning directions of urban farming were presented.

Micro-structure components applied to various disciplines are steadily demanded with lighter weight and better quality. This is because that ultra thin-wall injection molding has been paid attention with a lot of benefits such as cost reduction, shorter process period, and so forth. However, this technology is complicate and difficult to obtain high quality of products compared with conventional injection molding due to warpage caused by uneven shrinkage and molecular orientation. Since warpage of products directly affects product quality and overall performance of devices, it is essential to predict deformation behavior to achieve high precision of molded products. Therefore, this study aims to find out adequate thin-wall mold design for FPC connector housing by employing Moldflow simulation before application. In addition, experimental research is performed by using a fabricated mold structure based on simulated results to prove accuracy and reliability of the suggested simulation for warpage analysis.

The purpose of this study is to analyze physical characteristics, spatial composition, and using behavior of lounges in elderly skilled nursing facilities as spaces for activity programs and also to evaluate the spaces with the framework based on the indices for performing activity programs in elderly facilities. The results of the study were as follows: First, the lounge of an independent type ensured the privacy to perform programs, and so activities were managed more systematically. On the other hand, an expanded corridor type made the elderly feel difficult to pay attention to activities due to co-use of lounges and corridors. In a lounge of a hall type, the elderly had easy access to the place, but it also had weak home-like atmosphere because the space was used as a lobby entrance. Second, the facilities with western types of tables in whole lounges showed big changes in spatial composition, such as moving all the tables for any activities. It resulted in more preparation time and created obstacles in passages and space use. Third, in the evaluation of lounges based on the framework, most of lounges had accessibility of good quality, but they needed to improve home-like atmosphere and flexibility. To create home-like atmosphere, various spatial compositions and classifications in the lounge should be tried. Moreover, enough space and easy movable furniture can be considered for flexible spatial compositions.

Ecological corridor is the facility to connect two habitats fragmented by roads, dam, housing and industrial area. Critics of faunal corridors have suggested that they are simply an untested application of unproved island biogeography theory. But, everyone agree that ecological corridor is important useful structural components that help animal movement in fragmented landscapes. There are 52 ecological corridors in Korea. We investigated 43 ecological corridors of these and recorded the size of corridor, planting species, management and growth condition. We compared planting species to nearby exiting vegetation species and structure. We found that there are no considerations for many aspects of planting, for example, planting species, structure, animal migration and behavior, surrounding vegetation etc. Expecially, It was ignored management of plants, difference of surrounding vegetation, lacks of diverse planting species and structure. We suggest planting the native species of tall tree, shrub and ground cover, edge planting for transitional space between road and natural habitat, planting for foraging and breeding of target animal, diverse layer vegetation, and open space of center for rapid animal dispersal.
